TX 90' Civic SI w/high comp. jdm B20B

Really just testing waters. Like the title says its a 90' Civic SI. I swapped in a high compression jdm B20B(B20Z) with an estimated 30,xxx that I bought from JDM Engines Corp., innovative motor mounts, B18A1 intake mani., thermal intake gasket, ebay CAI,Blox FPR & gauge, DC 4-1 header to 2 1/2'' pipe(no cat) w/magnaflow muffler and is backed by a JDM Y1 tranny w/lsd, an oem replacement exedy clutch, and Fidanza lightweight flywheel(7.2 lbs). Also has innovative crossmember w/upgraded bushings, innovative shift linkage, blackworks racing half sized radiator w/fan, mizu hoses, B&M short shifter w/skunk 2 shift knob. Battery has been relocated to the back and doesnt sit quite right because its a bit big, but its the only one i had. Car is sitting on KYB shocks w/skunk 2 coilovers & 16'' Konig Zero-In's with 205/40 falken zeix ze 512's.

Bad:
1.Car is throwing a code 43 (fuel supply system) and is not running 100%, it is probably something simple but i cant figure it out and am tired of dealing with it.
2.I believe this is from the code, but when its cold early in the morning or late at night the car will start and die, but once it is warmer outside or after its been ran a while it has no issuse other than the code.
3.Exhaust obnoxiously loud
4.Needs new syncros
5.Is close to needing new tires
